Biotreatment of textile effluent in static bioreactor by Curvularia lunata URM 6179 and Phanerochaete chrysosporium URM 6181

Abstract

Investigations on biodegradation of textile effluent by filamentous fungi strains Curvularia lunata URM 6179 and Phanerochaete chrysosporium URM 6181 were performed in static bioreactors under aerated and non-aerated conditions. Spectrophotometric, HPLC/UV and LC-MS/MS analysis were performed as for to confirm, respectively, decolourisation, biodegradation and identity of compounds in the effluent. Enzymatic assays revealed higher production of enzymes laccase (Lac), lignin peroxidase (LiP) and manganese-dependent peroxidase (MnP) by P. chrysosporium URM 6181 in aerated bioreactor (2020; 39 and 392 U/l, respectively). Both strains decolourised completely the effluent after ten days and biodegradation of the most predominant indigo dye was superior in aerated bioreactor (96%). Effluent treated by P. chrysosporium URM 6181 accumulated a mutagenic metabolite derived from indigo. The C. lunata URM 6179 strain, showed to be more successful for assure the environmental quality of treated effluent. These systems were found very effective for efficient fungal treatment of textile effluent.

Enzyme production by immobilized Phanerochaete chrysosporium using airlift reactor

“…Recent results on the enzyme action of free P. chrysosporium URM6181 (Miranda et al, 2013) revealed also higher production of ligninolytic enzymes in an aerated bioreactor (Lac -2020, LiP -39 and MnP -392 U/L). The authors attributed these high enzyme activities to the addition of nitrogen in the medium.…”

Effects of gamma radiation on enzymatic production of lignolytic complex by filamentous fungi

“…An important factor to be taken into account is that most fungi producing enzymes of this class are higher fungi of the phylum basidiomycote that are very difficult to cultivate in the laboratory. Among the fungi called lower, we can highlight the anamorphic of ascomycote and basidiomycote and zigomycote that has been reported in the literature as promising for enzyme production since coloados under ideal conditions (Miranda et al, 2013). One alternative for improving the production of these enzymes by other groups of fungi is induced mutation by radiation, one widely used technique that contains antibiotics and drugs derived from microorganisms.…”
